The Bumble Hole Branch Canal.

The present day Bumble Hole Branch Canal and Bushboil Branch surround Bumble Hole, a water-filled clay pit, in Bumble Hole and Warren's Hall Nature Reserve, Rowley Regis, West Midlands, England. They formed a looped part of the original Dudley No. 2 Canal until the opening of the Netherton Tunnel in 1858 when the loop was bypassed by a new cut, in line with the new tunnel.

Part of the bypassed canal loop, which surrounds Bumble Hole is now in-filled giving access to the pool of Bumble Hole.

Between Windmill End Junction and the tunnel portal stands Cobb's Engine House, built in 1831 to pump water from coal mines into the canal.

The Bumble Hole railway used to cross the canal near Windmill End Junction, but was dismantled in 1969.
